Abstract

In a stapling device, a first guide member and a second guide member are disposed one by one on both sides of a binding portion of the recording medium on a side of a recording medium placing of a placement table such that each of the guide members is rotatable, and the first guide member and the second guide member are rotatable between a first posture along a first direction in which one abutting end side extends and a second posture inclined with respect to the first direction in line symmetry with respect to an imaginary line that passes through the binding portion along a second direction orthogonal to the first direction.

First claim

What is claimed is:

1. A stapling device comprising:
a main body section;
a binding processing section that is provided at the main body section and has a function of binding a plurality of recording media at a binding portion located at an end portion of a recording medium;
a pair of guide members that positions the plurality of recording media while an end side of the recording medium located outside the binding portion abuts against the guide members;
a placement table that is coupled to the main body section and has a placement surface on which the recording medium is placed; and
a base that is provided at an opposite side of the placement table from a side where the guide members are arranged, and pivotally supports a pair of gears,
wherein the guide members are disposed on both sides of the binding processing section on a side of the placement surface of the placement table such that the guide members are configured to each rotate, and are configured to rotate between a first posture along a first direction in which the end side that abuts against the guide members extends and a second posture inclined with respect to the first direction in line symmetry with an imaginary line that passes through the binding portion along a second direction orthogonal to the first direction in an extending direction of the placement surface, and
wherein each of the guide members is coupled to each of the gears, is pivotally supported by a shaft that penetrates the placement table, and moves between the first posture and the second posture by rotating the gear.

2. The stapling device according to claim 1 , wherein the gear is provided with a lever coupled to the gear, and by movement of the lever, the gear rotates and the guide member rotates.

3. The stapling device according to claim 1 , further comprising:
a support base that is attached to the main body section to be configured to move along the second direction, and to which the base is pivotally supported to be configured to rotate; and
an operating section that is supported by the main body section in an opposite direction to the binding portion, in the second direction,
wherein the support base moves in the second direction by a rotation operation of the operating section.

4. The stapling device according to claim 1 , further comprising:
a support base that is attached to the main body section to be configured to move along the second direction, and to which the base is pivotally supported to be configured to rotate;
a pushing and pulling section that is coupled to the support base in an opposite direction to the binding portion, in the second direction; and
a slide guide section that is provided in the main body section and guides movement of the pushing and pulling section along the second direction,
wherein the support base moves in the second direction by a pushing and pulling operation of the pushing and pulling section.

5. The stapling device according to claim 1 , wherein the base includes a knob section configured to move the guide member in a rotational direction.

6. A stapling device comprising:
a main body section;
a binding processing section that is coupled to the main body section and has a function of binding a plurality of recording media at a binding portion located at an end portion of a recording medium;
a pair of guide members that positions the plurality of recording media;
a placement table that is coupled to the main body section and has a placement surface on which the recording medium is placed; and
a support base that is attached to the main body section such that the support base is configured to move along a second direction,
wherein the guide members are disposed on both sides of the binding processing section, and have a first surface along a first direction in which one end side of the recording medium located outside the binding portion extends and a second surface that abuts against any of two end sides that form a corner portion of the recording medium when the recording medium is placed such that the corner portion is located on an imaginary line that passes through the binding portion along the second direction orthogonal to the first direction in an extending direction of the placement surface,
wherein the guide member is coupled to the support base and moves in the second direction together with the support base.

7. The stapling device according to claim 6 , further comprising:
an operating section that is supported by the main body section in an opposite direction to the binding portion, in the second direction,
wherein the support base moves in the second direction by a rotation operation of the operating section.

8. The stapling device according to claim 6 , further comprising:
a pushing and pulling section that is coupled to the support base in an opposite direction to the binding portion, in the second direction; and
a slide guide section that is provided at the main body section and supports the pushing and pulling section to be configured to slide,
wherein the support base moves in the second direction by a pushing and pulling operation of the pushing and pulling section.

9. A recording apparatus comprising:
a recording section that performs recording on a recording medium; and
the stapling device according to claim 1 .
